To all whom it may concern:

Be it known that I, Gaonon An'rus, a citizen of the United States.residin at Clear Lake, in the county of Deuel an State of South Dakota,have invented certain new and useful Improvements in Automatic Gasoleneand Oil Venders, of which the following is a specification.

This invention relates to vending machines for dispensing liquidsautomatically in a measured amount corresponding to the denomination ofthecoin inserted.

The main objects of my invention are to provide an apparatus dispensingliquids of different grades which can be predetermined by the purchaserand in varying amounts automatically controlled by the denomination ofthe inserted coin.

The invention will be understood from the following detailed descriptionin connection I with the accompanying drawings, in which Figure l is adiagrammatic view of anapparatus embodying my invention; and Fig. 2 is adetail view of a modified form of one of the parts. For the purposes ofclearness I have not shown the sup orting framework. A suitable numberof coin chutes 1 graduated in size to receive coins of differentdenominations' are provided which lead to the shallow grooves 2, 2,etc., in the coin-cylinder 4, these grooves being a depth to permit thecoin to project beyond the periphery of the cylinder. Corresponding withthe grooves and in a position to be engaged by the coins when thecylinder 4 is rotated, are a series of swinging levers 6, 6, pivoted attheir upper ends 6 A coin in one of the grooves will engage one lever orthe other, pushing it away from the cylinder, and. actin through thelinks 8, 8, rotates the bell-era g the dog 15, carried by the arm 12, toswmg the weighted inverted pendulum 17, forward upon the horizontalpivot 18. As the dog 15, slips off the side of the pendulum rod 16, thespring 19, causes the pendulum to fly back with suflicient force tostrike a hammer blow upon the lug 20, thereby rotating the switch 21 andcausing the blade 23 to engage the contact- 24, thus closing the circuitof the electric motor 25,

connected to the pump 26. This movement of the switch, acts through thelink 28,- to

lever 9, 10, 12, upon its pintle 14, and cans lift the arm 30, pivotedat 31, and which will return the swltch to off position when it isengaged by one of the stop lugs 32, 33, 35 or 36, in a mannerhereinafter described.

When the pump 26 is driven by the motor, the gasolene or other liquidwill be pumped from the main supply pipe through the pipe 38, into thedispensing tank 40. As the tank is being filled the float 42, rises andcauses the cable 43 to gradually lower the cross-head 45, carrying thestop rods 46, 47, until one of thestop-lugs strikes the arm 30, causingit to descend and swing the switch 21 to the of! position with the blade23 resting upon a back-stop 22, thereby breaking the circuit andstopping the motor.

I have shown four stop lugswhich are adjustable on the rods 46, 47 andare arranged atdiiferent elevations corre 0ndinigl with differentquantities of liqui that w tor operates for correspondng periods oftime. These stops may be set to different .points on the rOdS inaccordance with the be pumped into the tank when the mo- Patented Feb.5, 1918.

are suspended from the block or cross-head 45, carried by the swivel 49on the end of the cable 43. g

The pump may be connected to either supply pipes 56, or 57 so thatdifferent grades of oil may be supplied. This may be con-' trolled brocking the control lever 60, either to the right or to the left,thereby swinging the valve 61, to open communication with one supplypipe or the other. Then by pushing the lever forward the link 62, andarm 63 will turn the guide 51 causing the block 45 to turn on theturnbuckle 49 as a pivot and bring the rod 46 adjacent the lever 30 sothat the stops 32 and 33 will be in alinement therewith. By pulling thecontrol lever 60 in the opposite direction, the link 62 will swing theblock 51 in the reverse direction to thereby oscillate the block 45 onthe pivot 49, bringing the rod 47 adjacent the lever 30 and the stops35, 36

in alinement therewith. These preliminary will cause the actuation ofthe pendulum 17 to throw the switch 21 and thereby close the circuitthrough the motor 25. The manner in which the different coins determinethe particular stop that shall engage the lever 30 is as follows :If acoin is inserted in slot 2, the lever 6 will be engaged by the coin whenthe cylinder 4 is rotated by the handle 7, pushing the lever back andcaus-v ing the bar 11 to oscillate in a clockwise direction upon itspintle 13, thereby swingin the arm .70, in a clockwise direction ancausing the bell-crank 71- to move on its pivot 2 in a direction to %ushthe link 74. and guide 50 forwardly. he rod 46 will thus be swung towardthe arm 30, causing the lower, shorter stop 32 to be in direct verticalalinement with said arm. Under these conditions, the float 42 in thetank can only rise until the cable 43 descends sufficiently to cause thelower sto 32 to strike the arm 30 and lower it sufficiently to open theswitch 21 thus breaking the motor circuit.

If, however, the proper coin is inserted in the slot 2*, the rotation ofthe cylinder 4 thereby oscillat ng will cause the lever 6 to swingbackward,

the bar 11 in an anticlockwise direction and causing the bellcrank 71 topullthe guide 50 backward. This movement swings the rod 46 away from thearm 30 sufliciently to move the lower stop 32 out of alinement with thearm 30 but leaving the longer upper sto 33, still projecting thereover.Consequent y the motor will continue to operate until the float hasrisen to a higher level, sufiicient to permit the descending stop 33, toengage the lever 30, to open the switch 21 in the manner described. Ihave deemed it suflicient for purposes of illustration to show two coinslots and the mechanism controlled thereby to determine the period ofoperation of the motor driven pump, but it is obvious that I may provideany desired number of coin slots with a corresponding number ofcooperating elements to effect the proper movement of the stops.

Instead of placing the arm 30 at one side.

of the stop rods, I may place it between the rods; and I may alsoplaceupon one bar 46' as-shown, for instance, in Fig. 2, the bar being turnedaxially by the lever 60 in substantially the manner previouslydescribed.

The valve 75, in necting with the hose open and be automaticallvmaintained closed while the tank is being filled in any suitable manner,as for instance by connection with all of the stops the outlet pipe 76,COI1- 78, may be normally the float or with an operating part of the I Ium I have shown the valve controlled by suitable lever mechanism 80,with a centrifugal governor 81, on the shaft of the pump. When the pumpis in operation the valve will be maintained closed, and will be openedwhen it stops, permitting the contents of the tank to flow out throughthe hose 7 8 and nozzle 79.

I The operation of my liquid vender will be understood from theforegoing detailed description. When oil. or other liquidol differentgrades is supplied, the particular grade or quality is determined by thelateral movement of the control lever 60, and the set of quantity stopscovering the range of prices which include the coin which is to.

'to swing the pendulum 17, and cause it to rebound with a hammer blowupon the lug .20, causing the switch arm 23 to close the circuit of themotor 25 to thereby actuate the pump 26. The particular denomination ofthe coin deposited controls the direction of movement of the bar 11, andthe consequent swinging movement of the rods 46, 47 which determines theparticular stop lug that shall engage the arm 30, to open the motorswitch when the tank .float has risen sufiiciently to lower said stop.Upon the stoppage of the motor and pump the valve 7 5 automaticalllyopens to discharge the contents of the tan I have particularly describedthe mechanism illustrated in the accompanying drawings for the expresspurpose of clearly disclosing an embodiment of my invention but I amaware that various changes and modi fications can be made within thescope of my claims and without in any manner departingfrom the scope ofmy invention.
